trap may be of any Well v.ltnoivn construction but the trap Within itself forms no specific part of the present invention. The bath tub pipes 13 and 8 are shown conventionally A The lavatory pipe 1.3 connected to the 'l' head 2 in substantially the saine manner as the bath tub pipe and a trap 1G provided. ,l have illustrated the trap 16 located substantially directly below the lavatory boivl 17 and when connected as illustrated there need be no provision for back vent for the lavatory. Another advantage in Connecting the lavatory as shown is that the distance betiveen the lavatory and the venty and soil pipe head T and its integral elbow is materially shortened, which is an'ilnportant feature, Giving to the taet that.

in inany instances the rules and regulations of cities require that the lavatory be located within a given distance ot the soil or waste pipe connection.

bendable material, such as brass, but of suliicient rigidity tor the purpose intended.

constituting a soi and vent pipe, said elbow portion located between the ends of the Vent and soil pipe portions ot the head and pro vided with screw threaded apertures in the alls thereot', the Walls ot said apertures inclined toward'the soil pipe portion of the head and the vent pipe portion of 'the head and the vent pipe provided with' apertures, said apertures located above the horizontal portion ot the elbow, substantially as and for the purpose speeilied.
